winfrom窗体应用

winform窗体输入身份证号码从txt文档中获取省份信息并判断出性别和出生年月

private void button1_Click(object sender, EventArgs e)
{
    idNumber = textBox1.Text;
    
    if (idNumber.Length != 18)
    {
        MessageBox.Show("身份证号码无效！");
        return;
    }
    
    var provinceData = System.File.IO.ReadAllLines("sfzsb.txt", System.Text.Encoding.UTF8)
        .ToDictionary(x => x.Split(',')[0], x => x.Split(',')[1]);
    string province = provinceData[idNumber.Substring(0, 2)];  
    
    string genderDigit = idNumber.Substring(16, 1);
    string gender = "";

    if (int.Parse(genderDigit) % 2 == 0)
        gender = "女";
    else
        gender = "男";

    string year = idNumber.Substring(6, 4);
    string month = idNumber.Substring(10, 2);
    string day = idNumber.Substring(12, 2);
    string birthday = $"{year}-{month}-{day}";

    MessageBox.Show($"省份：{province}\n性别：{gender}\n生日：{birthday}");
}

• 这篇博客: C# Winfrom 常用功能整合-1中的 Winform 用线程写入TXT文件，并更新UI和进度 部分也许能够解决你的问题, 你可以仔细阅读以下内容或跳转源博客中阅读:
  

• 效果：

  

  UI控件定义如下

  共有三个控件，一个按钮：Button_Write，一个进度条：ProgressBar_WriteProgress，一个Label：Label_WriteStatus

  新建脚本 DataWrite 用来管理写入操作

  using System;
  using System.IO;
  using System.Text;
  using System.Windows.Forms;
   
  namespace Winform_vs2022
  {
      public class DataWrite
      {
          //声明一个更新主线程的委托
          public delegate void UpdateUI(int step);
          public UpdateUI UpdateUIDelegate;
          //声明一个在完成任务时通知主线程的委托
          public delegate void AccomplishTask();
          public AccomplishTask TaskEndCallBack;
   
          private string Path = Application.StartupPath + "\\test.txt";
   
          public void Write(object lineCount)
          {
              StreamWriter writeIO = new StreamWriter(Path, false, Encoding.GetEncoding("gb2312"));
              string head = "编号,省,市";
              writeIO.Write(head);
              for (int i = 0; i < (int)lineCount; i++)
              {
                  writeIO.WriteLine(i.ToString() + ",湖南,衡阳");
                  //写入一条数据，调用更新主线程ui状态的委托
                  UpdateUIDelegate(1);
              }
              //任务完成时通知主线程作出相应的处理
              TaskEndCallBack();
              writeIO.Close();
          }
   
          public DataWrite()
          {
              if (!File.Exists(Path))
              {
                  Console.WriteLine("文件不存在");
              }
          }
      }
  }

  Form1.cs

  
  using System;
  using System.Threading;
  using System.Windows.Forms;
   
  namespace Winform_vs2022
  {
      public partial class Form1 : Form
      {
          public Form1()
          {
              InitializeComponent();
          }
   
          private delegate void AsynUpdateUI(int step);
          private DataWrite DataWrite = new DataWrite();
   
          private void Button_Write_Click(object sender, EventArgs e)
          {
              //任务量为10000
              int taskCount = 10000; 
              this.ProgressBar_WriteProgress.Maximum = taskCount;
              this.ProgressBar_WriteProgress.Value = 0;
              //绑定更新任务状态的委托
              DataWrite.UpdateUIDelegate += UpdataUIStatus;
              //绑定完成任务要调用的委托
              DataWrite.TaskEndCallBack += Accomplish;
   
              Thread thread = new Thread(new ParameterizedThreadStart(DataWrite.Write));
              thread.IsBackground = true;
              thread.Start(taskCount);
          }
   
          //更新UI
          private void UpdataUIStatus(int step)
          {
              //如果是跨线程访问，就切换线程，否则直接更新UI
              if (this.InvokeRequired)
              {
                  this.Invoke(new AsynUpdateUI(delegate (int s)
                  {
                      this.ProgressBar_WriteProgress.Value += s;
                      this.Label_WriteStatus.Text = this.ProgressBar_WriteProgress.Value.ToString() + "/" + this.ProgressBar_WriteProgress.Maximum.ToString();
                  }), step);
              }
              else
              {
                  this.ProgressBar_WriteProgress.Value += step;
                  this.Label_WriteStatus.Text = this.ProgressBar_WriteProgress.Value.ToString() + "/" + this.ProgressBar_WriteProgress.Maximum.ToString();
              }
          }
   
          //完成任务时需要调用
          private void Accomplish()
          {
              MessageBox.Show("任务完成");
          }
      }
  }

  这里可以看出：

  更新UI数据用的是委托，和网上一些帖子的区别是，这里在UI线程中定义了一个委托进行执行的，而进度条的进度则是遍历时，for循环中的 i 的值，线程除了UI线程之外，也只是开启了一个线程
